Third Perek, Fourth Mishna

Expanded Translation

One woman had a Chatos and one woman had
an Olah. They also had an undesignated pair which was owned by
both of them in partnership and a designated pair that was owned
in partnership. If the Kohain brought them all at the upper part
of the Mizbayach as Olos, half are kosher and half are possul.
If he brought all at the lower part as Chato'os, half are kosher
and half are possul. If he brought half at the upper part as
Olos and half at the lower part as Chato'os, that is, he brought
one bird from each pair as an Olah and one as a Chatos, only the
undesignated pair is kosher, and it is divided between them.

Cases of the Mishna

Rochel was obligated to bring one Chatos and two Olos. Leah was
obligated to bring two Chato'os and one Olah. Rochel and Leah
jointly bought three kinim. At the time of purchase they
designated one bird of the first kain as Leah's Chatos and the
other as Rochel's Olah. Of the second kain they designated a
bird as a Chatos and a bird as an Olah without specifying the
woman to which each bird belongs. The remaining kain was left as
a stuma.

First Case

The Kohain mistakenly brought all six birds as Olos.

Din

The two birds that were designated as Olos and one bird of
the kain stuma are kosher. The other three birds are possul.
Rochel and Leah bring three more birds as Chato'os according to
their original obligations. These are definite obligations, not
sfaykos.

Second Case

The Kohain mistakenly brought all six birds as Chato'os. The din
is analogous.

Third Case

The Kohain brought one bird of each pair as a Chatos and one as
an Olah.

Result in the Worst Case

The two designated Olos were brought
as Chato'os, and the two designated Chato'os were brought as
Olos. The kain stuma was properly brought in any event.
[Diagram 36]

Din

The Chatos of the kain stuma fulfills a Chatos obligation
of one woman, and the Olah fulfills an Olah obligation of the
other woman. The women jointly bring another kain with the
understanding that the new Chatos will be for the woman who was
credited with the first Olah, and the new Olah will be for the
woman who was credited with the first Chatos.

In addition, the woman whose original obligation included a
second Chatos must bring another Chatos. The woman who was to
bring two Olos must bring another Olah. (Based on Rashi Maseches
Zvochim, daf 67:2, dibbur hamas'chil chetzyan l'maalah.)
